Neil Metals is a reputable manufacturer and supplier of Stainless Steel 316 Hollow Bars, located in Kolkata, India. They provide top-notch, corrosion-resistant stainless steel solutions suitable for a variety of industrial applications. Renowned for their precision in manufacturing and commitment to international quality standards, Neil Metals offers SS 316 hollow bars that are perfect for marine, chemical, pharmaceutical, and food processing industries. These hollow bars are particularly valued for their outstanding resistance to pitting, crevice corrosion, and harsh acidic environments. With state-of-the-art facilities and a robust distribution network, Neil Metals guarantees timely delivery and reliable product performance both domestically and internationally.
Stainless Steel 316 Hollow Bars consist of 16–18% chromium, 10–14% nickel, and 2–3% molybdenum, along with low carbon content and small amounts of manganese, silicon, phosphorus, and sulfur. The inclusion of molybdenum significantly boosts resistance to chlorides and corrosive substances. SS 316 boasts a tensile strength of about 515 MPa and a yield strength of roughly 205 MPa. It retains excellent mechanical properties across a range of temperatures, offering superior formability and weldability. The hollow design not only saves material but also reduces weight while ensuring strength and durability.

SS 316 hollow bars offer superior corrosion resistance compared to other stainless steel grades, particularly against chlorides and acidic environments. It performs better than SS 304, making it ideal for harsh environments like marine, chemical, and coastal applications.
Key factors to consider when selecting SS 316 hollow bars include corrosion resistance, mechanical strength, temperature tolerance, application environment, and required dimensions. It's essential to assess the project's chemical exposure, structural requirements, and the need for durability over time.
These Stainless Steel 316 Hollow Bars are extensively utilized in applications that demand strength, corrosion resistance, and weight efficiency. They are commonly found in heat exchangers, marine shafts, process piping, pharmaceutical equipment, and food-grade machinery. Additionally, these bars are employed in structural applications where internal flow or material reduction is essential, such as in hydraulic cylinders, rollers, and architectural supports. The resistance of SS 316 to seawater and aggressive chemicals makes it an excellent choice for coastal and offshore projects. Its versatility, hygienic properties, and high performance under pressure and heat make it a go-to option for challenging industrial environments.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
